Because in\nthis case a page can have multiple buffers and even if a page is not\nuptodate, some buffers can be uptodate.\n\nSo I suggest that when all buffers which correspond to a part of a file\nthat we want to read are uptodate, use this pagecache and copy data from\nthis pagecache to user buffer even if a page is not uptodate. This can\nreduce read IO and improve system throughput.\n\nI wrote a benchmark program and got result number with this program.\n\nThis benchmark do:\n\n 1: mount and open a test file.\n\n 2: create a 512MB file.\n\n 3: close a file and umount.\n\n 4: mount and again open a test file.\n\n 5: pwrite randomly 300000 times on a test file. offset is aligned\n by IO size(1024bytes).\n\n 6: measure time of preading randomly 100000 times on a test file.\n\nThe result was:\n\t2.6.26\n 330 sec\n\n\t2.6.26-patched\n 226 sec\n\nArch:i386\nFilesystem:ext3\nBlocksize:1024 bytes\nMemory: 1GB\n\nOn ext3/4, a file is written through buffer/block.

To avoid breaking code\ndo_pipe is now a small wrapper around do_pipe_flags. Once all callers are\nchanged over to do_pipe_flags the old do_pipe function can be removed.\n\nThe following test must be adjusted for architectures other than x86 and\nx86-64 and in case the syscall numbers changed.\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n#include \u003cfcntl.h\u003e\n#include \u003cstdio.h\u003e\n#include \u003cunistd.h\u003e\n#include \u003csys/syscall.h\u003e\n\n#ifndef __NR_pipe2\n# ifdef __x86_64__\n# define __NR_pipe2 293\n# elif defined __i386__\n# define __NR_pipe2 331\n# else\n# error \"need __NR_pipe2\"\n# endif\n#endif\n\nint\nmain (void)\n{\n int fd[2];\n if (syscall (__NR_pipe2, fd, 0) !\u003d 0)\n {\n puts (\"pipe2(0) failed\");\n return 1;\n }\n for (int i \u003d 0; i \u003c 2; ++i)\n {\n int coe \u003d fcntl (fd[i], F_GETFD);\n if (coe \u003d\u003d -1)\n {\n puts (\"fcntl failed\");\n return 1;\n }\n if (coe \u0026 FD_CLOEXEC)\n {\n printf (\"pipe2(0) set close-on-exit for fd[%d]\\n\", i);\n return 1;\n }\n }\n close (fd[0]);\n close (fd[1]);\n\n if (syscall (__NR_pipe2, fd, O_CLOEXEC) !\u003d 0)\n {\n puts (\"pipe2(O_CLOEXEC) failed\");\n return 1;\n }\n for (int i \u003d 0; i \u003c 2; ++i)\n {\n int coe \u003d fcntl (fd[i], F_GETFD);\n if (coe \u003d\u003d -1)\n {\n puts (\"fcntl failed\");\n return 1;\n }\n if ((coe \u0026 FD_CLOEXEC) \u003d\u003d 0)\n {\n printf (\"pipe2(O_CLOEXEC) does not set close-on-exit for fd[%d]\\n\", i);\n return 1;\n }\n }\n close (fd[0]);\n close (fd[1]);\n\n puts (\"OK\");\n\n return 0;\n}\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nSigned-off-by: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nAcked-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nCc: Michael Kerrisk \u003cmtk.manpages@googlemail.com\u003e\nCc: \u003clinux-arch@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "da3bbdd4632c0171406b2677e31494afa5bde2f8", "tree": "6a1947b2a32041ef0d14044e659ba7d546d55483", "parents": [ "3c82d0ce2c4f642b2f24ef98707a030543b06b90" ], "author": { "name": "Kentaro Makita", "email": "k-makita@np.css.fujitsu.com", "time": "Wed Jul 23 21:27:13 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jul 24 10:47:15 2008 -0700" }, "message": "fix soft lock up at NFS mount via per-SB LRU-list of unused dentries\n\n[Summary]\n\n Split LRU-list of unused dentries to one per superblock to avoid soft\n lock up during NFS mounts and remounting of any filesystem.\n\n Previously I posted here:\n http://lkml.org/lkml/2008/3/5/590\n\n[Descriptions]\n\n- background\n\n dentry_unused is a list of dentries which are not referenced.\n dentry_unused grows up when references on directories or files are\n released. This list can be very long if there is huge free memory.\n\n- the problem\n\n When shrink_dcache_sb() is called, it scans all dentry_unused linearly\n under spin_lock(), and if dentry-\u003ed_sb is differnt from given\n superblock, scan next dentry. This scan costs very much if there are\n many entries, and very ineffective if there are many superblocks.\n\n IOW, When we need to shrink unused dentries on one dentry, but scans\n unused dentries on all superblocks in the system. For example, we scan\n 500 dentries to unmount a filesystem, but scans 1,000,000 or more unused\n dentries on other superblocks.\n\n In our case , At mounting NFS*, shrink_dcache_sb() is called to shrink\n unused dentries on NFS, but scans 100,000,000 unused dentries on\n superblocks in the system such as local ext3 filesystems. I hear NFS\n mounting took 1 min on some system in use.\n\n* : NFS uses virtual filesystem in rpc layer, so NFS is affected by\n this problem.\n\n 100,000,000 is possible number on large systems.\n\n Per-superblock LRU of unused dentried can reduce the cost in\n reasonable manner.\n\n- How to fix\n\n I found this problem is solved by David Chinner\u0027s \"Per-superblock\n unused dentry LRU lists V3\"(1), so I rebase it and add some fix to\n reclaim with fairness, which is in Andrew Morton\u0027s comments(2).\n\n 1) http://lkml.org/lkml/2006/5/25/318\n 2) http://lkml.org/lkml/2006/5/25/320\n\n Split LRU-list of unused dentries to each superblocks. Then, NFS\n mounting will check dentries under a superblock instead of all. But\n this spliting will break LRU of dentry-unused. So, I\u0027ve attempted to\n make reclaim unused dentrins with fairness by calculate number of\n dentries to scan on this sb based on following way\n\n number of dentries to scan on this sb \u003d\n count * (number of dentries on this sb / number of dentries in the machine)\n\n- ToDo\n - I have to measuring performance number and do stress tests.\n\n - When unmount occurs during prune_dcache(), scanning on same\n superblock, It is unable to reach next superblock because it is gone\n away. We restart scannig superblock from first one, it causes\n unfairness of reclaim unused dentries on first superblock. But I think\n this happens very rarely.\n\n- Test Results\n\n Result on 6GB boxes with excessive unused dentries.\n\nWithout patch:\n\n$ cat /proc/sys/fs/dentry-state\n10181835 10180203 45 0 0 0\n# mount -t nfs 10.124.60.70:/work/kernel-src nfs\nreal 0m1.830s\nuser 0m0.001s\nsys 0m1.653s\n\n With this patch:\n$ cat /proc/sys/fs/dentry-state\n10236610 10234751 45 0 0 0\n# mount -t nfs 10.124.60.70:/work/kernel-src nfs\nreal 0m0.106s\nuser 0m0.002s\nsys 0m0.032s\n\n[akpm@linux-foundation.org: fix comments]\nSigned-off-by: Kentaro Makita \u003ck-makita@np.css.fujitsu.com\u003e\nCc: Neil Brown \u003cneilb@suse.de\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: David Chinner \u003cdgc@sgi.com\u003e\nCc: \"J.

For more information on how to use this\npatch, Chris Friedhoff has posted a nice page at\nhttp://www.friedhoff.org/fscaps.html.\n\nChangelog:\n\tNov 27:\n\tIncorporate fixes from Andrew Morton\n\t(security-introduce-file-caps-tweaks and\n\tsecurity-introduce-file-caps-warning-fix)\n\tFix Kconfig dependency.\n\tFix change signaling behavior when file caps are not compiled in.\n\n\tNov 13:\n\tIntegrate comments from Alexey: Remove CONFIG_ ifdef from\n\tcapability.h, and use %zd for printing a size_t.\n\n\tNov 13:\n\tFix endianness warnings by sparse as suggested by Alexey\n\tDobriyan.\n\n\tNov 09:\n\tAddress warnings of unused variables at cap_bprm_set_security\n\twhen file capabilities are disabled, and simultaneously clean\n\tup the code a little, by pulling the new code into a helper\n\tfunction.\n\n\tNov 08:\n\tFor pointers to required userspace tools and how to use\n\tthem, see http://www.friedhoff.org/fscaps.html.\n\n\tNov 07:\n\tFix the calculation of the highest bit checked in\n\tcheck_cap_sanity().\n\n\tNov 07:\n\tAllow file caps to be enabled without CONFIG_SECURITY, since\n\tcapabilities are the default.\n\tHook cap_task_setscheduler when !CONFIG_SECURITY.\n\tMove capable(TASK_KILL) to end of cap_task_kill to reduce\n\taudit messages.\n\n\tNov 05:\n\tAdd secondary calls in selinux/hooks.c to task_setioprio and\n\ttask_setscheduler so that selinux and capabilities with file\n\tcap support can be stacked.\n\n\tSep 05:\n\tAs Seth Arnold points out, uid checks are out of place\n\tfor capability code.\n\n\tSep 01:\n\tDefine task_setscheduler, task_setioprio, cap_task_kill, and\n\ttask_setnice to make sure a user cannot affect a process in which\n\tthey called a program with some fscaps.\n\n\tOne remaining question is the note under task_setscheduler: are we\n\tok with CAP_SYS_NICE being sufficient to confine a process to a\n\tcpuset?\n\n\tIt is a semantic change, as without fsccaps, attach_task doesn\u0027t\n\tallow CAP_SYS_NICE to override the uid equivalence check. But since\n\tit uses security_task_setscheduler, which elsewhere is used where\n\tCAP_SYS_NICE can be used to override the uid equivalence check,\n\tfixing it might be tough.\n\n\t task_setscheduler\n\t\t note: this also controls cpuset:attach_task. Are we ok with\n\t\t CAP_SYS_NICE being used to confine to a cpuset?\n\t task_setioprio\n\t task_setnice\n\t\t sys_setpriority uses this (through set_one_prio) for another\n\t\t process. Need same checks as setrlimit\n\n\tAug 21:\n\tUpdated secureexec implementation to reflect the fact that\n\teuid and uid might be the same and nonzero, but the process\n\tmight still have elevated caps.\n\n\tAug 15:\n\tHandle endianness of xattrs.\n\tEnforce capability version match between kernel and disk.\n\tEnforce that no bits beyond the known max capability are\n\tset, else return -EPERM.\n\tWith this extra processing, it may be worth reconsidering\n\tdoing all the work at bprm_set_security rather than\n\td_instantiate.\n\n\tAug 10:\n\tAlways call getxattr at bprm_set_security, rather than\n\tcaching it at d_instantiate.\n\n[morgan@kernel.org: file-caps clean up for linux/capability.h]\n[bunk@kernel.org: unexport cap_inode_killpriv]\nSigned-off-by: Serge E.

With preallocation, applications\nalso get a guarantee of space for particular file(s) - even if later the\nthe system becomes full.\n\nCurrently, glibc provides an interface called posix_fallocate() which\ncan be used for similar cause. Though this has the advantage of working\non all file systems, but it is quite slow (since it writes zeroes to\neach block that has to be preallocated). Without a doubt, file systems\ncan do this more efficiently within the kernel, by implementing\nthe proposed fallocate() system call. It is expected that\nposix_fallocate() will be modified to call this new system call first\nand incase the kernel/filesystem does not implement it, it should fall\nback to the current implementation of writing zeroes to the new blocks.\nToDos:\n1. Implementation on other architectures (other than i386, x86_64,\n and ppc). Patches for s390(x) and ia64 are already available from\n previous posts, but it was decided that they should be added later\n once fallocate is in the mainline. Hence not including those patches\n in this take.\n2. Changes to glibc,\n a) to support fallocate() system call\n b) to make posix_fallocate() and posix_fallocate64() call fallocate()\n\nSigned-off-by: Amit Arora \u003caarora@in.ibm.com\u003e\n" } ], "next": "3bd858ab1c451725c07a805dcb315215dc85b86e" }
